摘要
本文介绍了用 A1 - A2 / O工艺结合流化床技术对攀钢高浓度焦化废水进行 NH3 - N、COD降解的中试试验。试验结果表明 :当进水 NH3 - N<5 0 0 mg/ L、COD<2 0 0 0 m g/ L 时 ,该工艺可以实现 NH3 - N去除率 97%以上 ,COD去除率 85 %以上 ,酚去除率 99.9%。药剂及动力费用为 6 .6元 / t水 ,停留时间 5 0
This paper introduces the pilot-scale of the treatment of high density NH 3-N and COD in coke-chemical wastewater combine biology fluidized bed reactor withA 1-A 2-O process.When the density of NH 3-N<500 mg/L and COD <2 000 mg/L, NH 3-N removal percentage was more than 97 %, while COD removal percentage was more than 85 % and phenol removal percentage was 99.9 %, the cost of medicament and motive power was 6.6yuan per ton water, the retention period was 50 hour.
